Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

In the work the current state is analyzed and the relevance of investigations of the process of magnetic pulse welding of flat parts from similar and dissimilar metals is confirmed. The results of investigations of possibility of realization of magnetic pulse welding of flat specimens on the modified serial installation N-126A by means of experimental pancake rectangular inductor are given. The scheme of the process is given. The technology of producing joints of flat metal parts with a thickness of 1.0...1.5 mm from similar materials from aluminum A5N and AMg2 alloys, as well as from dissimilar – copper, A5N and AMG2 alloy with stainless steel 12Kh18N10T (hardened) is described. The carried out metallographic examinations showed that common for magnetic pulse welding of similar and dissimilar metals is a specific joining of welding plates in the areas equidistant from the center of the flat coil of the inductor. The thickness of the moving plates decreases, and the microhardness in the welding zones increases. The quality welding was fixed within the two-zone shape of joining. The quality of the welded joint was evaluated by the results of mechanical strength tests. 10 Ref. 1 Tabl., 9 Fig.
